You don’t want to find out your wiper blades are malfunctioning when it’s snowing or raining out. If your blades aren’t making contact with the windshield, chattering, or streaking, it usually signifies that it’s time to replace your blades. After all your wiper blades are made out of soft rubber and will wear out. It’s usually good to get blades replaced twice a year no matter how often you use them. Damaged or cracked blades can potentially scratch your windshield. If you have any questions about your windshield wipers you should contact Ferber's Tire and Auto Service where we can provide a quality inspection!
